Aroid Potting Mixes in Australia: Why Not All Are the Same

When it comes to aroids - anthuriums, philodendrons, monsteras, and alocasias - the aroid potting mix you choose can make a huge difference. Not all aroid mixes are created equal, and using the wrong one can slow growth, reduce leaf size, or even stress roots. - Australia's best Aroid Potting Mixes >>

At HiGrow, we design each aroid mix for specific plant needs and growing conditions. HiGrow Aroid AirLite is a fast-draining, airy mix perfect for high-humidity environments or for growers who water frequently. Its open structure prevents waterlogging, giving roots the oxygen they need to thrive. HiGrow Aroid Classic, on the other hand, strikes a balance between moisture retention and aeration, making it ideal for most indoor aroids in moderate humidity. For plants that enjoy consistent moisture, such as many tropical philodendrons and anthuriums, HiGrow Aroid AquaMax potting mix holds water slightly longer while still allowing air to circulate, reducing the risk of root rot in slower-drying environments.

One of the key differences between HiGrow blends and many off-the-shelf aroid mixes is longevity and stability. Mixes that include compost may seem nutrient-rich initially, but compost breaks down over weeks and months, compacting the substrate and reducing root aeration. HiGrow mixes - including AirLite, Classic, and AquaMax - are 100% soilless, made with stable components like coco, perlite, coco chips, and LECA. This means your mix maintains structure for many months, supporting healthy root systems and strong leaf growth without the compaction issues common in compost-based blends.

While aroids are resilient and can survive in very airy, fast-draining mixes, there’s a trade-off. If the substrate is too dry or lacks sufficient moisture retention, roots may struggle to access consistent water. This doesn’t usually kill the plant, but it does slow growth significantly. Leaves emerge smaller and take longer to unfurl, and overall development can lag compared to a mix that balances aeration with steady moisture. For optimal growth, aroids need a substrate that keeps roots oxygenated without letting them dry out completely - a balance that HiGrow mixes, like Aroid Classic and AquaMax, are specifically designed to achieve.

Choosing the right HiGrow aroid mix helps your plants thrive in their environment, whether you’re watering frequently, maintaining high humidity, or growing delicate tropical varieties. For Australian growers who want predictability, healthy roots, and consistent growth, HiGrow Aroid potting mixes offer the tailored solution every collector needs.
